EN10305-2 E355 OD12 Improved Surface Welded Steel Tube , Cold Drawn Steel Tube For Camshaft

Description:

Cold drawn welded pipe, it is the production of one of the best choice of the multistage hydraulic cylinder tube, its process and precision seamless steel tube cold drawing process, is to use precision resistance welding (ERW) precision drawing, manufacturing the EN 10305-2 eu mechanical cold drawn steel tube welding standard.

Chemical Compositions:

Manufacture Process:

According to EN10305-2 standard, Cold drawn on ERW tubes, make the tubes have high strength ,high quality, and to be seamless.

The cold rolled welded tube is produced by drawing ERW (electric resistance welded tube).During this process the sizing (wall thickness, inside and outside diameter), as well as weld integrity and surface finish is closely controlled to produce tube of the required size and mechanical property characteristics.

Main Date:
